Lenovo is at the Consumer Electronics Show in Las Vegas with its ThinkPad Helix, a combination tablet and Ultrabook laptop. When its fully docked it looks like a typical Lenovo laptop but the screen separates from the main housing, given you a tablet you can talk around with. You can also bend the screen back against the unit in case you want to walk around with a tablet and still have access to the keyboard.
The 3.7 pound device has an 11.6 inch “10 point multi-touch screen” and comes with a digitizer pen. You can also use your fingers but the pen provides finer point, so to speak.
Lenovo claims 10 hour battery life though I didn’t get to test it long enough to find out. There are batteries in both the screen and the main unit.
The Helix will be available later this quarter. Pricing hasn’t been announced
